To all whom it may concern:

Be it known that I, DiiNiEL M. PFAUTZ, a citizen of the United States, residing at Germantown, in the county of Philadelphia and State of Pennsylvania, have inventedI certain new and useful' improvements in Elevated-Railway Systems, of which the following is a specification.

My invention has `relation-in an elevated railway to the generalconstruction and ar-A rangement of the superstructure thereof.

The principal object of my invention is to with the accompanying drawings, forrriing part hereof, in whchfFigure l is' an end elevational view of an elevated-railway structure embodying.main features of niy invention. Fig. 2 is a side elevational view thereof. Fig. 3 illustrates Iin top or 'plan view a portion'of the structure. Fig. 4 is an end elevational view of a portion of the elevated-railway structure anda car enlarged, illustrating the manner of sup.- porting the same in suspended condition` from the lsaid structure; and Fig. 5 is a, longi` tudinal sectional'view of the upper portion of the structureenlarged, illustrating in side elevation the car and the means for" supporting and propelling the same along the structure. V

Referring to the drawings, a and a represent columns suitably connected to and supported by pedestals n.2 and (L3, located back of the curb-line andA adjacent to the sidewalks of* anda,5 of a'street or roadway c, so as to oifer no obstruction-to the street O/r roadway. These columns o, and ai', as shown inFig. 2,

are arranged vat suitable distances apart oneither side of the street or roadway, and to each` pair of oppositely-arranged columns a and a is suit-ably secured a cross-.girder a? of open-web orlattice work, s panni ng the entire street 0,6. Midway between the columns a ando and a proper distance apart' are arranged two longitudinal'lattice-girders and b', suitably secured to saidcross-girders a7, which support the saine.

These longitudinal vgirders b and b are furthermore rigidly connected with the cross-girders by lattice brackets 'a8 and c", and a similar pair of brackets al and c connect the cross-girders a7 withv the supporting-colunins a and a. In order to avoid vibrations and deiiections of the longitudinal girders b and b the same are A braced laterally by lattice-work(-1)2 and cross- 4beams?)3 and, stiffened by tie-rods b* and bf', passing over saddle-pieces cl2, secured to the top Aof the columns a. and a. The said Inannerof forming the cross-girders @Tand longitudinai girders t and b and bracing .and

stiffening thesaine gives a structure not only easyto erect, but also light in weight and rigid without in any way offering* an obstruction to light and air in the streetand. the adjoining buildings along which the structure passes.

The foregoing character .of structure pre;

sents little surface to the pressureof the Wind and resists the sway et passing cars `suspended from the same at a height sufiicient toperinit the passage cf vehicles or the'like beneath the cars. The structure'is also espe-1 cially adapted to support lamps for lighting the streets and sidewalks and the telegraph, telephone, and other electric wires, which otherwise are lcarried by separate poles, and

also to properly protect the same against the elements.

To the lower inner flanges be and t7 of the longitudinal girders b and are secured rails bs and b". Above these rails .bsjand b are secured to the longitudinal girders band b guard-rails b10 and blt, adapted to 'prevent .provided with rear and front platforms d? and d3 and dashboards dand d5, andwithin the same is arranged'asuitable: metal framework, (not shown,) to which the brackets d and d7 ofthetruck d are secured. In the IOC IOC

- 5. ing d1, within which an electric motor l(not bracketsda and J7 are arranged the bearings for the axles d8 and d, as shown in Figsrland To the axles d8 and d is secured'a vhoustion of two parallel series of columns, a series porting a track upon which a car is adapted o1u vertically-arranged cross-girders uniting the upper ends of opposite columns in series,`

two parallel longitudinal girders suspended from `beneath the cross-girders and each supto travel, ,-a guard-rail for said car, anda bracket for each longitudinal girder adapted to connect the outside' of said girder directly with the under -side yof the cross-girder,sub

stantially as and forthe purposes described.

2. In an elevated railway, the combination of two parallel series of columns, -a-series of vertically-arranged cross-girders uniting the upper ends of opposite columns in series, two parallel longitudinal 'girders suspended from beneath the cross-'girders and each supporting 'a track upon which -a vcar is adapted to travel, -a guard-rail for said car, brackets for each longitudinal -girder-and column, said 'brackets connecting the outside off said girders and the inside of'said columns directly to the under side of the .crossdgirden substantially as and for the purposes described.

3.y In an elevated railway, thecombination rof two longitudinal girders each supporting a track upon whichthe vehicle is adapted to travel, braces-spanning and tying the upper faces of the longitudinal girders -together and closing the same at their upper ends, and tie-rods lconneetedfwith said lon gitudinal girders and passin over columns to connect both of said longitudinal girders with each of said columns, substantially as and for the purposes described.

4. In an-elevated railway,` the combination of two aral'lel'series of columns, a series of cross-gir ers connecting the upper ends of opposite columns in series, two parallel longitudinal girders suspended from the :crossgirders and each supporting a track upon which a car is adapted to travel, braces spanning and tying t e longitudinal girders together at their upper faces, and tie-rods connected with said longitudinal lgirders and passing over said columns to connect -both of the-longitudinal girdersv with eachofsaid'col-l umns, substantially as and for the purposes described.

.5. In an elevated railway, the combination of two parallel series of columns, a series of cross-girders unitingthe upper ends of opposite columns in series, two parallel longitudinal gi-rders suspended from beneath the cross-girders and each supporting a Atrack upon which a car'is adapted to travel, brac-es 'spanning and tying the longitudinal girders together at their upper faces, tie-rods ycofnnec-ted with t-he upper faces of said longitudinal girders and passing over said columns to lconnect the longitudinal girders and col-j umns. adapted to connect .the outside lofthe longitudinal girdersaud the inside of said columns directly to the Vunder side of -said 'eross-girders, substantially as and for the purposes described.

16. In an elevated railway,.-the combination of two parallelseries Aof columns, a series of vertically-arranged.-crossJgirders uniting the upper ends of said opposite columns, two

paral'lei longitudinal gii'ders suspended from thecross-girders and each supporting a track upon which a' car is adapted -to travel, guardrails arranged intermediate of the upper and lower faces of said long gyi-tudinal girders and above the tracks thereof, brackets for each longitudinal girder adapted to connect the outside of said girders directly to the under side of the cross-girdersand braces spa-1min and tying the upper faces fof the longrtudina gir-ders toget-her, substantially as and -for the purposes described. '7. In an elevated railway, the combination of two parallel series of columns, a series ef vertically-arranged cross-girders uniting, lthe upper ends of said opposite col=un1ns,t-wo

parallel longitudinal .girders suspended from` beneath the cross-girders and each supporting a track upon 4which a car is adapted'to travel, brackets suspended from `beneath the cross-girders intermediate of the longitudinal Uirders and adapted to support a hood, a trol-y .ey-wire arranged in said hood and-carried -by the'same and said brackets, substantial-ly as and for the purposes|described` In testimony whereof I have hereunto set my signature, in the resenoe of two subscrib-` in witnesses, at Phi adel hia, Pennsylvania, th1s-22d day of May, A. 1906,.
